People will give you abstract answers to a question like this.

For something concrete, I suggest sticking to C syntax like languages like c#/js/java and even python to some extent. As history would show, the most popular languages seem to follow this syntax and it's fairly easy to pick up new languages based off experience. I went from c++->delphi->c#->js relatively easily.

My personal opinion as well is that now is the time to start getting into security software, pentesting etc. The proliferation of new languages, frameworks and api's is a pandoras box waiting to be opened by the security community. We've barely scratched the surface, as today's security community is really, really far behind. Once they catch up, and more automated tools and exploits start showing up that target these newer applications, these hipster startup companies will be forced to start spending. Right now it's mostly financial institutions, and companies using legacy stacks like php, wordpress, drupal that are being attacked.

That or data science/parallel programming.
